Coat the bottom of a baking pan with olive oil; create one layer of fillets on the bottom of the pan. Into a mixing bowl, combine tomatoes, parsley, basil, Italian seasonings, garlic, parsley salt, and salt and pepper. Pour mixture on top of the fillets in pan. Bake fish at 350ºF for 15 minutes uncovered. Remove pan from oven and top fish with grated cheese. Place back into the oven for 5-8 minutes, allowing the cheese to melt and the fish to finish cooking. However, do not let the fish overcook; when it pulls apart easily with a fork, it is done.
